Snell's law of refraction can be written as sin i = n sin r, where n is the refractive index from air to water, i is the angle of incidence, and r is the angle of refraction.

In an experiment where a ray of light is directed from air into water, if the angle of incidence is 46 degrees, choose 1 option which gives the angle of refraction predicted by Snell's law, correct to 2 significant figures, given that n = 1.208.

A) 0.84 degrees

B) 0.85 degrees

C) 23 degrees

D) 36 degrees

E) 37 degrees

F) 45 degrees

G) 46 degrees

H) 47 degrees

Can anyone help please?
